IMPROVEMENT lN MACHINES FOR MANUFACTURING CARDS FOR CARDING FIBERS.

Specification forming part of Letters Patent N 0. 186,396, dated January16, 1877; application filed To all whom it may concern: v

Be it known that we, THOMAS EDWARD YATES, HENRY YATES, WILLIAM HEATONKELLETT, andSIMON KnLL TT,a1l of Oleckheaton, in the county of York,England, have invented certain Improvements inMachines for ManufacturingCards for Oarding Fibers, of which the following is a specification:

This invention has for its object improvements in machines employed inthe manufacture of cards, or card-teeth employed for carda ing fibers,and relates specially to that class of card-tooth the working portion ofwhichi that is to say, from the points to the bendl the ordinarydescription.

Figure 1 is a plan view of part of a card-;

setting machine, having our improvements applied. Fig. 2 is a verticalsection of Fig. 1. Fig.3 is a cross-section on line a b; Fig. t, asection on the line 0 d.

A is an eccentric on the main driving-shaft of the machine. Bis aT-shaped lever, rocking on its ends in the pedestals G D. At E is anupright projection, being part of the lever B, and to which, by screw F,the adjust.- ing-piece G isattached. H is a die, secured by screw T tothe slide-block K. 'L is another and stationary die. It will be seenthat on each revolution of the main shaft the oc- November 11, 1876.

centric A will, by means of the T-lever, adjusting-pieceG, andslide-block K, cause the die H to advance upon the die L, and so nipwire between v flattened wire. When the eccentric has passed 1 itsgreatest throw, the pressure will be taken off the die H, whereon thespiral spring M will, by means of the pin N, draw back the slide K andthe die H away from the fixed die L, so that the ordinary teed of themachine may act, and another portion of wire will be brought between thedies to be flattened, and so on at each revolution of the shaft andeccentric. The adjusting-screw F and piece G admit of the degree offlattening imparted to the wire, being regulated with nicety. The diesmay also be regulated laterally by means of the screws S and T, and at Pand R are screws for adjusting the block W relatively to the slide-pieceK.

We claim- The combination of the stationary die L, and guides at eachside of the same, with the die H, slide K, adjustable shoe G on theactuating-lever B, and means substantially such as described forimparting to the said lever a vibratory movement, and substantially asspecified. a
